Late Blight reported! Blightling Aug 20, 2014
Late blight has been reported in a field of Russet Burbank processing potatoes in Sherburne County, MN by a local consultant. Disease is confined to one field and incidence is limited. The genotype has not yet been identified. This is the first report of late bight in our region. Growers should continue to apply protectant fungicides for both late blight and early blight and continue to scout for late blight. Morning dews that form this time of the year provide free moisture necessary for late blight infection.
